Subject: [Qemu-devel] [0/13] RFC: Guest visible IOMMU
Date: Thu, 22 Mar 2012 13:14:35 +1100 [thread overview]
Message-ID: <1332382488-12869-1-git-send-email-david@gibson.dropbear.id.au> (raw)
Here's another version of my series implementing the nevessary
framework for emulation of guest-visible IOMMUs. I've incorporated
the feedback from the last posting. I'm fairly confident that
preliminary patches 1-3 are ready to go in, the rest might still need
more consideration.
In particular, if anyone has thoughts on how to handle the case where
an IOMMU mapping is invalidated by the guest where a qemu-side device
currently has that piece of IOVA-space dma_memory_map()ed, I'd be
interested to hear it.
